An electrical contacting apparatus in an ink jet printer includes a plurality of spring elastic members corresponding to the contact portions of the ink cartridge. Each of the spring elastic members includes a contact portion which contacts a contact portion of the ink cartridge, a base having one end electrically connected to the printed circuit board, and a connection portion connected to the contact portion and the base for providing an elastic restoration force between the contact portion and the base. According to this structure, the contact resistance at the contact surface of a spring elastic member which contacts each of the contact portions of the ink cartridge is reduced, thereby improving the quality of printing.
